LOAD OF THE WEEK-
2009/11/13
Being eliminated in a shooting event is not something that settles well
with CURMUDGEON. C
will reach for his box of “special” loads thus avoiding the big “E”.
Here are a few of his undercover favorites.
Plus some SNAPPER (fast) 20-gauge 3” steel loads followed by
a big mouth comment or two.

CURMUDGEON COMMENT
“Can’t load it!”
“C” hears this!
The comment begins a Sherlock Holmes like review. From long
distance, and not being able to observe the load, loader or
techniques used, C is challenged to discover the fallacy.
Don’t be too hasty to bet on
the caller, as C often discovers reloading misapplications, or false
techniques and those floating bits of general confusion.
“Can’t load it”,
ignores the load has been previously put together and test fired by
the lab techs. So
SOMEBODY was able to produce this load and fire it.
But there are many slips between reading about a load and
pushing it through a reloading press.
From afar “C” yaks on the phone:
“Are you measuring the elements with a digital scale? (Good to get
it right.)
“What shot size are you using?” (Buckshot in a quail load?
How interesting.)
“Repeat the recipe for me!”
(That’s not right!)
“What reloading tool are you using?” (A pre-WWI table top tootise
toy.)
“Do you wish to bet your butt (twenty dollars will do) that “C”
can load it?”
Thus far this week “C” has uncovered the following.
Roll-crimping a fold-crimped load.
Does it matter?
Yes and no. (There is a MUCH longer answer and greater depth
here). Some propellants
(and this entails nearly all of the slower burn rate propellants) do
not take to roll-crimped loads.
Three points: (1)Some
hull plastics do NOT cooperate with roll-crimping.
(The good guys; FIOCCHI. MULTIHULL. RIO, FEDERAL, WINAA-HS).
(2) The roll-crimping desire may lack the needed tools, talent or
technique.
(3) The elements coming together may not be suitable for
roll-crimping. [Note: Roll crimping was used with black powder
loading and black powder burns INSTANTLY!
The slower the burn rate of the modern nitro-cellulose
propellant utilized - the LESS likely the roll-crimped load will
function without great ups/downs in pressure and velocity.
Dropping the elements.
The reloading person dropped (via bushing or scale) all the
elements into the hull. The last step in the process was to attempt
to fold-crimp the load. This may be reasonable
with simple loads in a short hull.
However, as we move away from target loads and into built-up
hunting loads (multiple layers) there is a NEED to compact as you
move along. Layer by layer.
This is a reloading technique!
Either you acquire it - or you don’t.
If you assemble all the
elements of a load in a stack before compressing, you may find your
fold-crimp impossible to apply.
You NEED to compress (not crush) in layers.
(Remember, somebody else made this load, so can’t you?)
Slow burn rate propellants
used in hunting loads are often spongy as pillows. (Air spaces in
propellants equal BAD LOADS.) Propellants
NEED to be compressed when the wad is placed in the hull. Once other
components stack, you have lost your chance to compact the
propellant. (Hunting
loads on a progressive loader?
You have to be nuts!)
The wad is difficult to get into the hull and sometimes “tips” from
the force applied.
Ah, precisely why God (and
BP) invented Mica Wad Slick (white mica dust).
Fired hulls retain a smooth exterior, but insides become
scoured with craters. (Rough as a cob).
A teaspoon of Mica Wad Slick into a bag of wads and presto!
The wad now slithers easily into the roughed up interiors of
fired hulls. For BP,
this is magic is now thirty years old.
And what is “C” doing with his odd moments?
Why playing with the NEW
nickel plated lead BUCKSHOT (OO @ .325” and 51.4 gr. Each) just
arrived at BP). The
penetration of these pellets is ENORMOUS!
Perfect for hunting or tactical loads.
